Cell Volume Regulation in the Nephron

Annual Review of Physiology, 1990
Nearly every cell in the kidney can volume regulate in response to a hypertonic challenge. Some are able to respond immediately to hyperosmotic media by a RVI. Other cells require stimulation prior to exposure to hyperosmolarity to demonstrate RVI. An increase of intracellular osmolytes during RVI usually occurs by an increase of NaCl influx either via

Cell Volume Regulatory Mechanisms

2006
Prerequisites for cell survival include avoidance of excessive alterations of cell volume. Cells counterbalance the osmolarity due to cellular accumulation of organic substances by uneven distribution of inorganic ions. They extrude Na(+) in exchange for K(+) by the Na(+) /K(+) ATPase. The cell membrane is less permeable to Na(+) than to K(+) . The K(+)

Cell volume and hepatocellular function

Journal of Hepatology, 1995
The hepatocellular hydration state, i.e. liver cell volume, is a dynamic parameter, which changes within minutes in response to alterations in the environmental or hormonal milieu. These changes in cell hydration act as a signal which modifies metabolism and gene expression due to complex alterations in protein phosphorylation.

Cell volume regulation in immune cell apoptosis

Cell and Tissue Research, 2000
The loss of cell volume is an early and fundamental feature of programmed cell death or apoptosis; however, the mechanisms responsible for cell shrinkage during apoptosis are poorly understood. The loss of cell volume is not a passive component of the apoptotic process, and a number of experimental findings from different laboratories highlight the ...

Pathophysiology of Red Cell Volume

2006
In the current work, we review three situations where red cell volume changes are important. Red cell apoptosis (eryptosis) accounts for the removal of ageing and damaged erythrocytes from the circulation by macrophages. Amongst other cellular responses, eryptosis is associated with net cytosolic KCl loss and concomitant cell shrinkage.

Cell Volume Studies in B‐Cell Leukaemia

British Journal of Haematology, 1980
Summary Leucocyte volume histograms were obtained in 12 cases of B‐chronic lymphocytic leukaemia (B‐CLL), two cases of B‐prolymphocytic leukaemia (B‐PLL) and two cases of hairy‐cell leukaemia (HCL) by means of a Coulter model ZB1 linked to a channelyser.

Cell volume and the regulation of apoptotic cell death

Journal of Molecular Recognition, 2004
AbstractApoptosis is a physiological mechanism allowing for the removal of abundant or potentially harmful cells. The hallmarks of apoptosis include degradation of cellular DNA, exposure of phosphatidylserine at the outer leaflet of the cell membrane and cell shrinkage.

Cell mechanical microenvironment for cell volume regulation

Journal of Cellular Physiology, 2019
AbstractCell volume regulation, as one of the fundamental homeostasis of the cell, is associated with many cellular behaviors and functions. With the increased studies on the effect of environmental mechanical cues on cell volume regulation, the relationship between cell volume regulation and mechanotransduction becomes more and more clear.

Cell Swelling and Volume Regulation

Canadian Journal of Physiology and Pharmacology, 1992
The extracellular space in the brain is typically 20% of the tissue volume and is reduced to at least half its size under conditions of neural insult. Whether there is a minimum size to the extracellular space was discussed. A general model for cell volume regulation was presented, followed by a discussion on how many of the generally involved ...

Cell volume, plasma volume, total blood volume and F_cells factor in the rhesus monkey

American Journal of Physiology-Legacy Content, 1958
Forty-two simultaneous measurements of plasma and cell volume with T-1824 and P32 were made on 18 normal monkeys ranging in weight from 3.4 to 7.1 kg. Nine determinations were made on two animals at varying intervals during a 16-month period. The mean values and standard deviations were as follows: cell volume 17.7 (S.D., 1.66) ml/kg; plasma volume ...
